摘要: 物质的硬度作为一个物理量已被广泛运用于各种研究领域。硬度测量在各种机械试验法中是最迅速、最经济的一种方法,而且材料硬度值与其它机械性能有一些相当精确的相应关系。有关硬度的各种测试方法已发展相当完善。同时,人们对硬度的微观机制也曾作了许多研究。

Abstract: An empirical correlation between the bond parameters and the hardness of binary crystal AN B8-N was derived: Hv=AN·Z/d6 exp(-0.6fi), Hm=0.675 Hv, where Hv-Vikers hardness, Hm-Mohs hardnss,Z-valence,d-bond length (10-10m), N-coordination number, fi-Phillips ionicity,A-constant,8467.5.This empirical correlation was used to calculate the hardness of 66 kinds of compounds. The calculated values of 36 kinds of them are in agreement with the experimental values.

Key words: crystal ANB8-N, hardness, chemical bond parameters
